Description

An electrocardiogram monitoring device for pediatric nursing

Technical Field

The invention belongs to the technical field of medical devices, and in particular relates to an electrocardiogram monitoring device for pediatric nursing.

Background technique

ECG monitoring device is a means of monitoring the electrical activity of the heart. Ordinary ECG can only simply observe the short-term ECG activity of the heart at the time of recording the ECG, while ECG monitoring is a non-invasive monitoring method that continuously observes and monitors the electrical activity of the heart through a display screen. It can obtain the patient's blood oxygen saturation, pulse rate and other vital signs data through a finger clip, provide reliable and valuable ECG activity indicators, and guide real-time processing. Therefore, it has important use value for patients with abnormal ECG activity, such as hypoxia, various arrhythmias, etc.

When existing ECG monitoring devices monitor the blood oxygen saturation of children or infants, they mostly obtain the vital sign data of young patients by clamping the fingers with a finger clip. Due to factors such as the strong clamping force of the finger clip, the activeness of children, and low pain tolerance, the clip is prone to fall off during the monitoring process, which leads to missing or erroneous vital sign data, which is not conducive to medical staff to accurately judge the physical condition of young patients. At the same time, the strong clamping force of the finger clip can also cause pain, resistance, crying, etc. in children, which is not conducive to the acquisition of vital sign data. Based on the above problems, this application document proposes an ECG monitoring device for pediatric care to improve the above problems.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

Please refer to the accompanying drawings 1 to 3, the present invention provides an electrocardiogram monitoring device for pediatric care, including a monitor body 100 and a lead cable 110, the lead cable 110 is assembled at one end of the monitor body 100, and the end of the lead cable 110 away from the monitor body 100 is equipped with a plurality of collection parts 200, the collection part 200 includes an anti-detachment sleeve 201, a collection sleeve 202 and a collection sensor 203, the anti-detachment sleeve 201 is arranged at one end of the monitor body 100, the collection sleeve 202 is rotatably connected to one end of the anti-detachment sleeve 201, the anti-detachment sleeve 201 and the collection sleeve 202 are both provided with finger through holes, and the guide tube 203 is provided with a finger through hole. The connection cable 110 and the anti-drop sleeve 201 as well as the lead cable 110 and the collection sleeve 202 are fixedly connected, and both ends of the collection sleeve 202 are provided with axle pins 204, and the anti-drop sleeve 201 and the collection sleeve 202 are rotatably connected through the axle pins 204. The anti-drop sleeve 201 and the collection sleeve 202 are close to each other and are located at the lower end of the axle pin 204. The stop surface 205 is inclined, and the intersection of the two stop surfaces 205 in the extension direction is located on the center line of the axle pin 204. The collection sensor 203 is fixed to the upper end inside the collection sleeve 202, and the lead cable 110 and the collection sensor 203 are electrically connected, and also includes:

The limiting part 300 is assembled on one side of the anti-dropping sleeve 201, and the limiting part 300 is connected to the shaft pin 204. The limiting part 300 can limit the rotation direction of the collection sleeve 202;

A support part 400, which is assembled inside the collection sleeve 202, and the support part 400 is matched with the collection sensor 203;

When the limiting part 300 is in the working state, the collection sleeve 202 can only rotate in the forward direction, and when the limiting part 300 is in the reset state, the collection sleeve 202 can only rotate in the reverse direction.

Specifically, the working state refers to the state of the limit portion 300 when the collection sleeve 202 is rotated to make the two stop surfaces 205 approach each other, and the reset state refers to the state of the limit portion 300 when the collection sleeve 202 is rotated to make the two stop surfaces 205 move away from each other.

Furthermore, the forward rotation is only described as a direction relative to the reverse rotation and does not constitute a limitation on the actual rotation direction of the collection sleeve 202.

Here, in the structure of human fingers, except for the thumb, the other fingers are composed of three knuckles. In order to better describe the working process of the present device, in this embodiment, the three knuckles of the fingers are named the first knuckle, the second knuckle and the third knuckle in the direction away from the palm to close to the palm.

In this embodiment, when obtaining vital signs data such as blood oxygen saturation and pulse rate of a young patient, the limiting part 300 is switched to the reset state, and the collection sleeve 202 is rotated until the collection sleeve 202 is located in the extension direction of the anti-detachment sleeve 201, and the limiting part 300 is switched to the working state. At this time, the collection sleeve 202 can only rotate forward, and the patient's fingers are passed through the anti-detachment sleeve 201 and the finger through holes inside the collection sleeve 202 in turn, so that the anti-detachment sleeve 201 is sleeved on the outside of the third finger joint, and the collection sleeve 20 2 is sleeved on the outside of the second knuckle, allowing the patient to bend the second knuckle by himself, so that the second knuckle rotates relative to the third knuckle, and the collection sleeve 202 is driven by the second knuckle to rotate in the direction close to the anti-drop sleeve 201. When the anti-drop sleeve 201 and the stop surface 205 at the upper end of the collection sleeve 202 are in contact with each other, the collection sleeve 202 stops rotating forward. At the same time, the limiting part 300 in the working state restricts the collection sleeve 202 from rotating in the reverse direction. Through the cooperation of the anti-drop sleeve 201 and the collection sleeve 202, the patient's hand The second and third knuckles of the finger are in a bent state, and a limit is formed on the second and third knuckles, the monitor body 100 is started, and the patient's vital sign data is collected by the collection sensor 203. The second and third knuckles in the bent state are limited by the cooperation of the anti-detachment sleeve 201, the collection sleeve 202 and the limit part 300, so that the anti-detachment sleeve 201, the collection sleeve 202 and the finger cannot be separated, and there is no need to assemble the collection part 200 on the finger by clamping, which will not cause pain to young patients. The patient can stop crying and make a fuss to ensure the integrity and accuracy of the collected vital sign data and avoid errors in the vital sign data. After the monitoring is completed, the limit part 300 is switched from the working state to the reset state. At this time, the collection sleeve 202 can only rotate in the opposite direction. The patient straightens the second finger joint by himself and drives the collection sleeve 202 to rotate through the second finger joint, so that the two stop surfaces 205 move away from each other until the collection sleeve 202 rotates to the extension direction of the anti-detachment sleeve 201. The patient can then take his fingers out of the anti-detachment sleeve 201 and the collection sleeve 202.

It should be noted that the acquisition sensor 203 is an existing mature technology, which performs calculations based on changes in light absorption during arterial pulsation. Two light sources located in the visible red light spectrum (660 nanometers) and the infrared spectrum (940 nanometers) alternately illuminate the tested area. The monitor body 100 calculates the ratio of these two spectra absorbed by the arterial blood and compares the result with the saturation value in the oximeter memory, thereby obtaining blood oxygen saturation and other vital signs data, which will not be further elaborated here.

Secondly, please refer to FIG. 3 again. When the collection sleeve 202 is located in the extension direction of the anti-drop sleeve 201, the angle between the two stop surfaces 205 is in the range of 60° to 120°. In this embodiment, the angle between the two stop surfaces 205 is preferably 90°.

In this embodiment, in the natural state, the maximum angle at which the second knuckle can rotate relative to the third knuckle is about 100° of the monitor body. By setting the angle between the two stop surfaces 205 to 90°, the device is made more ergonomic.

Next, please refer to FIGS. 4 to 6 , the limiting part 300 includes a bottom shell 301, a ratchet 302, a reversing ratchet 303, a ball 304, an elastic element 305 and a cover plate 306. The bottom shell 301 fixes one side of the anti-dropout sleeve 201, and an inner cavity 307 is provided inside the bottom shell 301. The ratchet 302 is fixed to the outer side of the shaft pin 204 and is located inside the inner cavity 307. The reversing ratchet 303 is rotatably connected to one side of the anti-dropout sleeve 201 and is located inside the inner cavity 307. The reversing ratchet 303 is adapted to the ratchet 302, and the ball 304 is elastic. The elastic element 305 and the cover plate 306 are provided on the bottom shell 301. The ball 304 is slidably connected to one end of the bottom shell 301 away from the ratchet 302, and the ball 304 and the reversing ratchet 303 are adapted to each other, the elastic element 305 is assembled between the bottom shell 301 and the ball 304, the cover plate 306 is fixed to one side of the bottom shell 301, one side of the reversing ratchet 303 passes through the cover plate 306, and the reversing ratchet 303 and the cover plate 306 as well as the shaft pin 204 and the cover plate 306 are all rotationally connected, wherein when the reversing ratchet 303 and the ratchet 302 are in contact, the reversing ratchet 303 can limit the ratchet 302.

Furthermore, when the limiting portion 300 is in the working state and the reset state, the contact points between the reversing ratchet 303 and the ratchet wheel 302 are different. Through the different contact points, the reversing ratchet 303 can limit the ratchet wheel 302 in different directions.

It should be noted that, in this embodiment, the inner cavity 307 is composed of two circular cavities, and the two circular cavities are interconnected. The cross-sectional shape of the inner cavity 307 is gourd-shaped through the cooperation of the two circular cavities, and the distance between the two centers of the circles inside the inner cavity 307 is less than the sum of the radii of the two circular cavities.

In this embodiment, when monitoring vital sign data of young patients, the limit part 300 is switched to the working state. At this time, the collection sleeve 202 can only rotate in the forward direction. After inserting the finger into the anti-drop sleeve 201 and the collection sleeve 202, the patient bends the second finger joint autonomously, and drives the collection sleeve 202 to rotate through the second finger joint. Since the shaft pin 204 is set on one side of the collection sleeve 202, the shaft pin 204 rotates synchronously with the collection sleeve 202. The ratchet 302 and the shaft pin 204 are fixedly connected, so that the shaft pin 204 drives the ratchet 302 to rotate, and the ratchet 302 and the reversing ratchet 303 cooperate with each other. , so that the ratchet 302 can only rotate in the forward direction, and then the collection sleeve 202 can only rotate in the forward direction, and then the second and third knuckles in the bent state cannot be taken out from the anti-detachment sleeve 201 and the collection sleeve 202. When the monitoring is completed, the reversing ratchet 303 is rotated to replace the contact point between the reversing ratchet 303 and the ratchet 302, so that the limit part 300 is changed from the working state to the reset state. At this time, through the cooperation of the reversing ratchet 303 and the ratchet 302, the collection sleeve 202 can only rotate in the reverse direction, and the patient can straighten his fingers and take them out from the anti-detachment sleeve 201 and the collection sleeve 202.

Secondly, please refer to Figure 7 again. A first ratchet tooth 311 is provided at the upper end of one end of the reversing ratchet tooth 303, a second ratchet tooth 312 is provided at one end of the reversing ratchet tooth 303 and located at the lower end of the first ratchet tooth 311, a first ball groove 313 is provided at the upper end of the other end of the reversing ratchet tooth 303, and a second ball groove 314 is provided at the lower end of the other end of the reversing ratchet tooth 303, and the ball 304 and the first ball groove 313 as well as the ball 304 and the second ball groove 314 are adapted to each other. When the first ratchet tooth 311 and the ratchet wheel 302 are in contact, the ratchet wheel 302 can only rotate forward, and when the second ratchet tooth 312 and the ratchet wheel 302 are in contact, the ratchet wheel 302 can only rotate in the reverse direction.

In this embodiment, please refer to Figures 5 and 7. When the limiting portion 300 is in the working state, the first ratchet tooth 311 contacts the ratchet 302. At the same time, the ball 304 contacts the second ball groove 314. When the collection sleeve 202 drives the ratchet 302 to rotate forward, the ball 304 is pushed to move through the first ball groove 313 to compress the elastic element 305. The first ratchet tooth 311 is driven by the teeth on the ratchet 302 to rotate in the opposite direction and disengage from the ratchet 302. At this time, the first ratchet tooth 311 cannot limit the ratchet 302 that rotates forward. At the same time, the elastic element 305 drives the ball 304 and the first ratchet tooth 311 to reset. If at this time, the collection sleeve 202 rotates in the opposite direction, and the ratchet 302 is driven to rotate in the opposite direction through the collection sleeve 202. Since the first ratchet tooth 311 is in contact with the ratchet 302, the first ratchet tooth 311 is driven to rotate forward through the ratchet 302. Since the distance between the two center points inside the inner cavity 307 is less than the sum of the radii of the two circular cavities, the reversing ratchet tooth 303 limits the ratchet 302, making it impossible for the ratchet 302 to rotate in the opposite direction, and further making it impossible for the collection sleeve 202 to rotate in the opposite direction. Similarly, when the limiting part 300 is in the reset state, the second ratchet tooth 312 is in contact with the ratchet 302, and at the same time, the ball 304 is in contact with the first ball groove 313, and the collection sleeve 202 can only rotate in the opposite direction.

It should be noted that FIG. 5 is only a schematic diagram of the internal structure of the limiting portion 300 when it is in the reset state.

Please refer to FIG. 6 and FIG. 7 again. A reversing groove 315 is formed on the side of the reversing ratchet 303 away from the anti-dropping sleeve 201. A reversing rod 308 is detachably inserted into the reversing groove 315.

In this embodiment, through the above-mentioned arrangement, after the medical staff switches the limit part 300 to the target state, they remove the reversing rod 308 to prevent children from accidentally switching the state of the limit part 300, and can effectively prevent children from secretly removing their fingers from the anti-detachment sleeve 201 and the collection sleeve 202.

Please refer to FIG. 6 and FIG. 8 again. An indication mark is provided on one side of the reversing ratchet 303. A plurality of status marks are provided on one side of the cover plate 306. The indication mark and the status mark are matched.

In this embodiment, the cooperation of the indication mark and the status mark makes it easy for medical personnel to understand the status of the limiting portion 300 , making the device easy to use.

Please refer to Figure 9 again. The support part 400 includes a guide column 401, a support plate 402 and a reset element 403. The guide column 401 is slidably connected to the inside of the collection sleeve 202. The support plate 402 is fixed to the upper end of the guide column 401 and is located inside the collection sleeve 202. The reset element 403 is assembled between the collection sleeve 202 and the reset element 403. A driving plate 404 is inclinedly opened at one end of the support plate 402 close to the anti-detachment sleeve 201.

In this embodiment, when the finger of a young patient is inserted into the collection sleeve 202 and the first knuckle contacts the driving plate 404, the first knuckle drives the support plate 402 to move away from the collection sensor 203, and the support plate 402 squeezes the reset element 403. After the second knuckle is inserted into the collection sleeve 202, the second knuckle can be supported by the cooperation of the reset element 403 and the support plate 402, so that the second knuckle can fit the collection sensor 203, which is convenient for the collection sensor 203 to collect the patient's vital sign data. At the same time, the device can adapt to fingers of different thicknesses and children of different ages, thereby improving the scope of application of the device.

Please refer to Figures 2 and 3 again. The upper ends of the anti-dropping sleeve 201 and the collection sleeve 202 are both provided with clamping bosses 206, and the lead cable 110 and the anti-dropping sleeve 201 as well as the lead cable 110 and the collection sleeve 202 are fixedly connected via the clamping bosses 206. The lead cable 110 passes through the two clamping bosses 206 and is connected to the collection sensor 203. The middle end of the lead cable 110 is provided with a telescopic section, which is located between the two clamping bosses 206 and is spiral.

In this embodiment, a spiral telescopic section is provided at the middle end of the lead cable 110 so that when the collection sleeve 202 rotates relative to the anti-drop sleeve 201, the telescopic section can adaptively adjust its length, making the device more practical.

Please refer to Figure 2, Figure 10 and Figure 11 again. The end of the anti-dropping sleeve 201 away from the collection sleeve 202 is slidably connected with the adjusting sleeve 207. Guide rods 208 are provided on both sides of one end of the adjusting sleeve 207. Among them, the outer side of one guide rod 208 is threadedly connected with a positioning knob 209. Guide grooves 210 are provided on both sides of the anti-dropping sleeve 201, and the guide rods 208 are slidably connected to the inside of the guide grooves 210.

When the positioning knob 209 and the anti-dropping sleeve 201 are tightly fitted, the adjusting sleeve 207 can be positioned by the cooperation of the positioning knob 209 and the anti-dropping sleeve 201 .

In this embodiment, the positioning knob 209 is rotated to disengage the positioning knob 209 and the anti-detachment sleeve 201, and the adjusting sleeve 207 is slid to adjust the length of the combination of the anti-detachment sleeve 201 and the adjusting sleeve 207. After the adjustment is completed, the positioning knob 209 is rotated in the opposite direction to make the positioning knob 209 fit tightly with the anti-detachment sleeve 201 again. The adjusting sleeve 207 is positioned by the cooperation of the positioning knob 209 and the anti-detachment sleeve 201. In the above scheme, since the length of the third knuckle of older children is longer than that of younger children, by adjusting the length of the combination of the anti-detachment sleeve 201 and the adjusting sleeve 207, the device can adjust the length of the combination of the anti-detachment sleeve 201 and the adjusting sleeve 207 according to the length of the third knuckle of the patient, and then adjust the length of the knot on the third knuckle to obtain a better fixing effect.

The working principle of the present invention is:

When obtaining vital signs data such as blood oxygen saturation and pulse rate of young patients, the limiting part 300 is switched to the reset state, and the collection sleeve 202 is rotated until the collection sleeve 202 is located in the extension direction of the anti-dropout sleeve 201, and the limiting part 300 is switched to the working state. At this time, the collection sleeve 202 can only rotate forward, and the patient's fingers are passed through the finger through holes inside the anti-dropout sleeve 201 and the collection sleeve 202 in turn, so that the anti-dropout sleeve 201 is sleeved on the outside of the third finger joint, and the collection sleeve 202 is sleeved on the outside of the second finger joint. At the same time, by resetting The cooperation of the element 403 and the support plate 402 makes the second finger joint of the patient fit with the collection sensor 203, allowing the patient to bend the second finger joint autonomously, so that the second finger joint rotates relative to the third finger joint, and the collection sleeve 202 is driven by the second finger joint to rotate in the direction close to the anti-drop sleeve 201. When the anti-drop sleeve 201 and the stop surface 205 at the upper end of the collection sleeve 202 fit each other, the collection sleeve 202 stops rotating forward. At the same time, the limiting part 300 in the working state restricts the collection sleeve 202 from rotating in the reverse direction. The cooperation of the collecting sleeve 202 makes the second and third knuckles of the patient's finger be in a bent state, and forms a limit on the second and third knuckles, starts the monitor body 100, and collects the patient's vital sign data through the collecting sensor 203. The cooperation of the anti-detachment sleeve 201, the collecting sleeve 202 and the limit part 300 forms a limit on the second and third knuckles in the bent state, so that the anti-detachment sleeve 201, the collecting sleeve 202 and the finger cannot be separated, and there is no need to assemble the collecting part 200 on the finger by clamping, which can prevent the young from being misunderstood. The patient experiences pain and cries, and to avoid errors in vital sign data, after the monitoring is completed, the reversing rod 308 drives the reversing ratchet 303 to rotate, and the limit part 300 is switched from the working state to the reset state. At this time, the collection sleeve 202 can only rotate in the opposite direction, and the patient straightens the second finger joint independently, and drives the collection sleeve 202 to rotate through the second finger joint, so that the two stop surfaces 205 move away from each other until the collection sleeve 202 rotates to the extension direction of the anti-detachment sleeve 201, and the patient can take his fingers out of the anti-detachment sleeve 201 and the collection sleeve 202.
